Lithium production wasnât always this simple, or this cheap. For almost half a century, starting in the early 1950s, the worldâs primary source of lithium was North Carolina, much of it from a mine in the town of Kings Mountain.
In comparison, the global reserves of lithium carbonate equivalentâwhich is the amount that can be economically mined right nowâis estimated to be about 75 million metric tons, according to the United States Geological Survey. The U.S. can only claim about 203,000 metric tons of those reserves right now.
